On Wednesday of this week English Class third graders had an impromptu visit from the fourth graders and their teacher. The fourth graders have been learning about simple machines and their teacher, Ms. Leena, has been taking a course about using Legos at school. Now they put all of this good knowledge to use and the fourth graders built a simple machine using Legos. To Ms. Sylvia’s great delight, the third graders remembered enough from their simple machines unit back in the second grade that they were able to identify the simple machine that the fourth graders constructed as a pulley. The apparatus really was impressive.
